vue.js - vue.js 组件需要 name 选项吗？

Question

如果我不在组件中设置名称，是否会导致任何问题？
即使我不设置它，我也可以使用它。

    <template>
      <div> some component</div>
    </template>
    
    <script>
    export default {
        name: "SomeComponent" // is this essential?
    };
    </script>

当注册一个组件时，它的 编号 是必需的，但 姓名 不是。
如 Vue Guide: Vue.component说:

Registration also automatically sets the component’s name with thegiven id.

因此，在声明一个组件时，将 component.name 留空就可以了。
但最好的做法是始终为您的组件命名。
因为(引用:Vue Guide: Vue.component options):

Allow the component to recursively invoke itself in its template. Notethat when a component is registered globally with Vue.component(), theglobal ID is automatically set as its name.

Another benefit of specifying a name option is debugging. Namedcomponents result in more helpful warning messages. Also, wheninspecting an app in the vue-devtools, unnamed components will show upas , which isn’t very informative. By providingthe name option, you will get a much more informative component tree.
